srnclmcnirion forming part of Letters Patent No. 661,551, dated November .13, 1900.

Application filed December 5, 1898. serial No. 698,322. W0 model;

To a 11/72/0721 it may concern:

Be it known that LCHARnns THOMAS Pow- ERS, gun and rifle maker, residing at Albert street, Brisbane, Queensland, have invented certain newand useful Improvementsin'lype- Writing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same.

My invention has relation to type-writing machines, and more especially to that type of machines wherein the impressions are obtained from a so-called type-wheel having one or more circular rows or fields of type as, for instance, small-case, capitals, and figures and symbols.

My improvements relate more particularly to the mechanism for positioning the typewheel to make an impression, and to effect this in the known machines the following, among other parts, have been necessary, namely: a ratchet or sprocket wheel; a stop plate therefor and two screws; a second heartshaped ratchet 01' sprocket Wheel and a shield therefor; a front-stop plate and two rivets; a front-stop spring and spring-stud and a front-stop adjustment and nut; a back-stop bail, bail-plate, and two screws; a back-stop bail-spring and stud and back-stop adjustment screw and nut; two backstop-holding plates and four screws; a main action-spring, main action-spring stud or main action-spring tension-cran k and screw.

My invention has for its object the simplification of the above-described mechanism by dispensing with the twenty-nine elements enumerated and substituting the following six elements: a stop-wheel, a locking device therefor and a retracting spring, a stopguide, a cam-lever, a lever actuated thereby, and a fulcrum-screw for said lever. In lieu of the spring heretofore used for returning the type-wheel rock-shaft into a normal position and attached to the upper frame and to a comparatively long radial arm on a sleeve on said shaft 1 mount said spring on the shaft itself.

'lhat my invention may be fully understood 1 will describe the same in detail, reference being bad to the accompanying drawings, in which- Figure l is a top plan View of a wheel typewriting machine, the general construction of which is well known, embodying my improve ments, the type-wheel being shown depressed asin the act of making an impression. Fig. 2 is a fragmentary cross-sectional view taken on or about on line 1 l of Fig. 10. Fig. 3 is a sectional detail view showing the normal relative positions of those parts which constitute my invention, the stop lock wheel being shown partly broken away. Fig. 4 is a view similar to Fig. 2, the section being taken about on line 3 3 of Fig. 10. Fig. 5 is a view similar to Fig. 3, showing the parts viewed from the right-hand side of the machine. Fig. 6 is a View similar to Fig. 2, the stop lock-Wheel being shown in section and the type-wheelin the position it assumes when a key has been partly depressed to revolve said wheel, and thereby position the particular letter, figure, or symbol for printing, the parts being shown approximately in their relative positions. Fig. 7 is a fragmentary detail sectiona view of Fig. 6, some of the parts being partly broken away. Fig. 8 isa view similar to Fig. 6, showing the typewheel fully depressed. Fig. 9 is a fragmentary sectional detail view of Fig. 8. Fig. 10 is a front elevation of a portion of the upper machine-frame and parts mounted therein. Figsll to l5are detail perspective views of the six mechanical elements above referred to and of the type-wheel-bearnecessary to describe in detail all of the parts of the machine, which will only be brieflyreferred to, with the exception of those parts with which my said improvements are directly connected.

In the drawings, F indicates the main fram- (star ing, andf the upper frame part, in which is journaled the type-wheel rock-shaft S. The key levers L are arranged in superposed banks, (three in the example shown in Fig. 1,) each bank being divided into two groups on either side of the central line of the machine intersecting the axis of rotation of the typewheel W and on either side of a spacing-lever L, arranged in or substantially in said central plane. The key-levers have hooked ends Z, hooking on a fulcrum-rod R, common to all the levers, and said key-levers have bearingshoulders 2 3. The shoulders 2 have bearing on rocking frames or short bails bone for each group of key-levers on either side of the spacing-lever L-while the shoulders 3 are adapted to bear on and depress a rocking frame or long bail b. The key-lever shoulders or bearing-surfaces 2 are all alike in position, while the relative position of the shoulders or beari rig-surfaces 3 varies, so that in a line of keys they will be graded consecutively for well-known purposes.

The key and spacing levers are guided in comb-plates p and p, and the platen P is mounted on a suitable carriage receiving its progressive or feed motion from a radial arm 5 on a sleeve S, Fig. 11, which in accordance with my invention has a second anglearm 5 provided with a guide-slot s for the type-wheel-locking pawl hereinafter referred to, and to the horizontal member of said angle-arm s proximate to the forward end of the slot .9 is secured in accordance with my invention a retarding-spring S hereinafter referred to, said sleeve S having hearings, one, .9 at the heel of angle-arm s and one, 5 axially and transversely of the sleeve for the type-Wheel spindle Siwhich extends,as usual, through the rock-shaft S, and thus also locks the sleeve S against rotation thereon. There is also provided the well-known mechanism for shifting the type-wheel spindle S in its hearings to bring one orthe other field of type into posit-ion for printing, the inner end of said spindle extending through a bracket 4 and carrying a lock-nut 5, said bracket having sliding motion in the slot of a suitable guide, the spindle being retracted by a suitable spring 6, the appliances for shifting said type-wheel spindle being controlled by special key-levers in a well-known manner.

The type is inked by a roller journaled in an arm depending from the loop or bailf on the upper frame portion f, in which loop the type-wheel vibrates.

Finally there are provided the usual sector-levers operating a pinion rigidly connected with the type-wheel and controlled by the type-key levers in a well-known manner and hereinafter to be referred to.

All of the parts above described, with the indicated exceptions, and others usually employed in type-writers, as the indicator or alarm, indicating when a line of writing is completed or about to be completed, the feed mechanism for the platen-carriage, &c., and

other parts which are unnecessary to the understanding of my invention are of any desired or well-known construction and opera- 7; tion, as hereinbefore stated, and need, therefore, no further elucidation.

On the type-wheel rock-shaft S is mounted a torsion-spring S Fig. 10, one end of which is secured tothe upper frame f, in which said shaft has its bearings, and the other end of said spring is secured to one of the sector-lever sleeves, which are rigidly secured to the shaft. By means of this spring the shaft S is returned to a normal position when moved out of it in writing, thus avoiding the long radial arm on the sleeve and the long retracting-spring hitherto used and connected to said arm and to the loopf of the upper frame f, whereby said retractingspring is also moved out of the way and the danger of its being injured in handling the paper-carriage and platen avoided.

The type-wheel \V is mounted on its spindle S so as to revolve freely, and below said wheel the said spindle carries a flanged sleeve 7, to the lower end of which is secured a pinion S. On the flange of the sleeve 7 is seated the stop-wheel W, and between said wheel W and a nut 9 and jam or look nut 10, screwed to sleeve 7 and which forms a hearing for the type-wheel, is secured a radial arm a, that carries a looking-pin a, which projects into a hole in the type and stop wheels W W, respectively, thus locking these parts together and to the pinion 8 in a wellknown manner and causing them to revolve synchronously.

The stop-wheel W is constructed in the form of a crown ratchet-wheel. having two series of teeth w in number equal to the number of type-key levers L, said two series of teeth being divided by a shorter tooth to and diametrically opposite the same bya tooth w, which is longer than the teeth 20 the two series of teeth being beveled in opposite directions, as shown more clearly in Fig. 15. The tooth to, which is shorter than the teeth 10 serves to hold the type-wheel W in a normal position or at a starting-point, while the tooth to, which is a little longer than the teeth n2 serves to prevent the type-wheel from making more than one-half of a revolutionin either direction under momentum when the outer or right-hand key-lever of the upper line or bank of such is depressed for positioning the letter J, j, or the symbol z for printing, requiring about half a revolution of the type-wheel W from left to right, Fig. 1, the, locking-pawl then engaging the space between said longer tooth to and the tooth 10 on the right thereof. (See Fig. 1.) This is also the case when the extreme left-hand key-lever of the upper line or bank of such is depressed to bring the letter Z, z, or [30 the symbol in position, which requires also about one-half of a revolution of said type-wheel in a reverse direction or from Hence in this arrangementthe right to left.

left-hand series of teeth w t'. 6., those on the left of the shorter andlongerteeth 10wcorrespond with the type-hey levers of the left-hand group of such or on the left of the spacinglever L, while the teethon the right of said shorter and longer teeth correspond with the type-leversof the right-hand group, special key-levers L being provided forshifting the type-wheel to print capitals, numbers, and symbols, as above explained.

It has hereinbefore been stated that the sleeve S, having radial arm 3, that actuates the feed mechanism of the paper or platen carriage, is held against rotating independently of the typewheel rock-shaft S through the type-wheel spindle S extending freely through suitable openings in said sleeve and shaft, and that said sleeve has an angle-arm s slotted at 3 Fig. 11, for the passage of a dog or pawl that serves to lock said wheel when rotated to a greater or less extent in one or the other direction by type-key levers L to bring a type corresponding with the depressed key-lever into position for printing. This rotation of the type-wheel is effected in a well'known man nor by two arms A respectively rising from the short bails b of the two groups of type-key levers L. Each of said arms terminates in a toothed rack adapted when a key-lever is depressed and through its bearing-face 2 to depress the short bail 1), corresponding with the group to which the depressed lever belongs, to gear with a toothed portion 12 on toothed sector-levers I), hereinbefore referred to, said levers being secured to the typewheel rock-shaft S on the opposite sides of the pinion 8, with their toothed segments in perpetual gear with said pinion in a well-known manner.

The sector-levers B in their normal position abut against two projections or buffers f f on the upper frame f, and in the slot or recess between said abutments works the lockingpawl presently to he referred to, so that when one of said sector-levers B is rocked by the depression of the short bail b it falls away from its buffer and rotates the pinion 8, the latter rolling down on the toothed segment of the stationary sector-lever, which is held to its bull-er by the reactive effect thereon of the said pinion. \Vhen, howeven, the type-key lever is further depressed, both sector-levers are caused to move with the rock shaft by well-known means,and during this operation the type-key lever depresses the long bail b by the action thereon of the bearingsurface 3 on said key-leve1z As soon as the type-wheel is positioned by the action ofa keylever L on bail Z) and the long bail b commences to move a toothed arm A on said bail comes into operation to lock said type-wheel. This is effected in accordance with myinvention, as follows: A locking-pawl 0 (shown in detail in Fig. 13) has an elongated slot 0, through which the roclcshaft S passes, so as to afford the necessary play to said pawl toward and from the crown ratchet-wheel W.

The said pawl is slightly bent to one side above its slotted portion and terminates in an overhangin flange 0, which has a perforated lip c and along one side of said overhanging flange extends the pawl-arm proper, 0 that projects through and is guided in the slot .9 in the angle-arm s of the sleeve S, hereinabove described. By the side of the lockingpawl C and loosely mounted on the typewheel rock-shaft S is a cam-lever D, (shown in detail in Fig. 12,) and provided with a toothed portion (7, adapted to be engaged by the toothed arm A", rising from the long bail I),

said cam-lever having stepped bearing-surfaces 61 (Z To the left-hand bu tfer f on the upper machine-framefis pivoted a lever E, (shown in detail in Fig. 14,) said lever having a lateral projection e, the under face 6 of which is preferably concave, so as to conform to the preferably convex bearing-surfaces d d of cam-lever D, though said bearing-surfaces may, if desired, be practically straight faces instead of convex and concave, respectively. The upper face c of lever E is convex to conform with the concave under side of the segmental flange 0 on the locking pawl C, said lever E lying normally between said flange c and the bearingface d on camleverD.

WVhen a type-key lever is depressed, the roclcshaft S is rocked toward the platen P, and therewith the type-wheel spindle S the stop-wheel \V, and the typewvheel W, the latter being at the same time revolved to the required extent by a sector-lever B. As soon as the key commences to depress the long bail 7') its arm A turns the cam-lever Din the same direction, thereby causing lever E to move from bearing-surface d on said camlever D to the bearing-surface d thereby lifting the lever E, and as it has bearing on the under side of flange 0 in locking-pawl C said pawl is moved toward the stop wheel \V and enters between two teeth thereof and looks it into position. This takes place immediately after a sector-lever B has positioned the type-wheel and before the rock-shaft S completes its motion toward the platen P. It will thus be seen that the amplitude of the throw or travel of the locking-pawl C is a uniform one, it having to-and-fro motion in a fixed lino relatively to the toothed flange on the stop-wheel \V, the return movement of the pawl being effected by a retracting spring 5 attached to lip c on tlangec of said pawl and to the cam-lever D at (1 Figs. 12 and 13. The simplicity of these devices compared with those heretofore employed for the same purposes will readily be understood.

In Figs. 2 to 5 I have shown the parts in their normal position and in Figs. 6 and 7 in the position when a key'lever has depressed its short bail 1) and is about to depress its long bail b, the locking-arm c of the locking-pawl being about to lock the stop-wheel W, and in Figs. 8 and 9 said parts are shown in their relative positions when both short and long bails are fully depressed and the type-wheel moved into contact with the platen P.

I have hereinbefore stated that the sleeve S, which actuates the feed mechanism for the platen-carriage and at the same time acts as a guide for the locking-arm c of the locking-pawl C, also carries a retarding-spring 8*, Fig. 11, so arranged that its bent free end will bear lightly on the vertical inner face of the toothed flange of the stopwheel W, so that when the machine is operated rapidly or the key levers depressed suddenly with greater force than is necessary the rotation of the type-wheel will be somewhat retarded, so as to insure its being locked as soon as it reaches the limit of its rotary motion, determined by the key struck. This spring may, however, be dispensed with, as the described mechanism has been found to operate in a perfect manner without it if at all properly handled.

Instead of operating the locking-pawl O, as above described, said pawl may be operated by means shown in Fig. 16, wherein g indicates a rod having an oblong aperture through which passes the type-wheel rock-shaft S, the rod being connected with the horizontal arm Z of a bell-crank lever Z, whose vertical arm Z has a longitudinal slot i curved at its upper end toward said horizontal arm. The long bail b has a projection to which is secured a pin b extending and lying normally in the upper curved end of slot Z so that when said long bail is depressed by a typekey lever the arm X will push the connectingrod upwardly, and as said long hail continues to move down the pin 1) will travel in the straight portion of the slot Z without affecting the connecting-rod g. The last-named rod carries a roller 1" in contact with the heel of the locking-pawl 0, whereby said pawl is moved toward and into engagement with the stop-wheel W. A spring 0 coiled about the stop-arm c and acting on a shoulder thereon or having its lower end secured thereto, while the upper end of said spring has bearing on the under side of the horizontal member of the angle guide-arm s on sleeve S, serves to retract the pawl from the stop-wheel.

Instead of the actuating-roller r the locking-pawl C may be provided with a flange c surrounding its oblong aperture 0, Fig. 17, on which flange is mounted the upper end of the connecting-rod g to move said pawl in one direction, the circular aperture in the rod being of a diameter equal to the longer diameter of the encompassing flange, as will be readily understood.
